Starting from the potent and selective but poorly brain penetrant 5-HT6 receptor antagonist SB-271046, a successful strategy for improving brain penetration was adopted involving conformational constraint with concomitant reduction in hydrogen bond count. This provided a series of bicyclic heteroarylpiperazines with high 5-HT6 receptor affinity. 5-Chloroindole 699929 combined high 5-HT6 receptor affinity with
从有效且选择性强但对脑渗透性差的5-HT6受体拮抗剂SB-271046开始,采用了一种成功的提高脑部渗透性的策略,该方法涉及构象约束并伴随着氢键数的减少。这提供了一系列具有高5-HT 6受体亲和力的双环杂芳基哌嗪。5-氯吲哚699929结合了高5-HT6受体亲和力和出色的脑渗透性,并且在大鼠和狗中都具有良好的口服生物利用度。
